Description
Technical field
The utility model relates to Blade measuring tool, the damping hole site measuring tool of especially a kind of blade.
Background technique
Some Steam Turbines have kind of a special vane, have damping hole in integral shroud, on back sagittal plane, install every two panels leaf when impeller
Piece sagittal plane is close together, and a straight pin passes through damping hole, increases the rigidity and vibration resistance of impeller with this, this two resistances
Not only aperture requires height in Buddhist nun hole, and the status requirement in hole is also very high, to guarantee that blade can achieve the effect that imagine in advance, needs
The blade produced is measured, whether detection damping hole site complies with standard.
Utility model content
The purpose of the utility model is to provide a kind of damping hole site measuring tools of blade, solve the above-mentioned prior art and ask
One or more in topic.
In order to solve the above technical problems, the technical solution of the utility model are as follows:
A kind of damping hole site measuring tool of blade, innovative point be, the structure include: blade, pedestal, square cotter and
Bolt offers damping hole at the integral shroud of blade, is one piece of H shape panel at the blade root of blade, and blade interlude is in arcuation, H shape
The upper and lower ends of panel all have groove, are equipped with baffle above the center of pedestal, square cotter is fixed on the left side of baffle, blade
The groove of root is placed on square cotter, and the depth of groove and the height of square cotter are identical, and bolt is fixed on the right side of baffle, and bolt is big
It is small in the same size with damping hole.
Further, square cotter and bolt, which are located at the position of baffle, is fixed according to production requirement.
Further, square cotter passes through baffle and is evenly distributed on baffle two sides.
Further, baffle right side opening perforation, bolt pass through eyelet and are flexibly connected with baffle.
Further, at the integral shroud of blade it is interior, back sagittal plane on be equipped with the identical damping hole of size.
The utility model has the beneficial effects that the utility model structure is simple, easy to use, inner face integral shroud damping hole and the back side
Integral shroud damping hole can be measured by this tool, and measurement method is convenient and quick, can accurately measure damping hole on blade
Whether position complies with standard with size.

Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in more detail.
A kind of damping hole site measuring tool of blade as shown in Figure 1 to Figure 3, the structure include blade 1, pedestal 2,
Square cotter 3 and bolt 4 offer damping hole 11 at the integral shroud of blade 1, are one piece of H shape panel 12 at the blade root of blade 1, in blade 1
Between section be in arcuation, the upper and lower ends of H shape panel 12 all have groove 13, and baffle 14, square cotter are equipped with above the center of pedestal 2
3 are fixed on the left side of baffle 14, and the groove 13 of 1 root of blade is placed on square cotter 3, the depth of groove 13 and the height of square cotter 3
Identical, bolt 4 is fixed on the right side of baffle 14, and 4 size of bolt and damping hole 11 are in the same size, the blade 1 in the utility model
For a kind of special vane, blade 1 is placed on pedestal 2 and measures, and bolt 4 is important measuring tool, the position of bolt 4 with
Size is all according to the design corresponding with size of the position of damping hole 11 on qualified blade.
Square cotter 3 and bolt 4, which are located at the position of baffle 14, to be fixed according to production requirement.
Square cotter 3 passes through baffle 14 and is evenly distributed on 14 two sides of baffle, and 14 two sides of baffle are respectively used for measuring the interior of blade 1
Sagittal plane and outer radial surface.
14 right side opening perforation of baffle, bolt 4 passes through eyelet and is flexibly connected with baffle 14, if the damping hole 11 of blade 1
When setting is qualified, bolt 4 can be embedded in damping hole 11, and bolt 4 can move in the eyelet of baffle 14, be convenient for measuring.
At the integral shroud of blade 1 it is interior, back sagittal plane on be equipped with the identical damping hole 11 of size.
It is close to the baffle 14 in measuring tool with 1 inner radial surface of blade when surveying inner face integral shroud damping hole 11, the blade root of blade 1 is put
It sets on square cotter 3, square cotter 3 provides support force to blade 1, allows blade 1 is stable to be placed on pedestal 2, while square cotter 3
Positioning action can also be played, when 1 blade root of blade has been close to the placement of square cotter 3,11 position of damping hole is surveyed with bolt 4
Amount, sees that can bolt 4 be embedded in damping hole 11, and blade 1 is carried on the back sagittal plane when testing back side integral shroud damping hole 11 and is close in measuring tool
Between baffle 14, measure whether 11 position of damping hole meets the requirements with size using bolt 4.
The protection scope of the present invention is defined by the appended claims and their equivalents.The above is only this
The preferred embodiment of utility model, it is noted that those skilled in the art, created not departing from the utility model
Under the premise of design, some similar deformation and improvement can be made, these also should be regarded as the protection scope of the utility model
Within.
